The new Nikon D7100 DSLR features a 24.1MP DX-format CMOS sensor and an
EXPEED 3 image processor, which work together to produce high resolution
still imagery and full HD 1080i/p video in multiple frame rates. Movie
recording is also benefitted through the inclusion of both external
microphone and headphone jacks as well as the ability to manual adjust
exposure settings during recording. A notable improvement in image
sharpness and resolution is afforded through the removal of the optical
low-pass filter, and a 51-point autofocus system with 15 cross-type
sensors ensures quick and precise focusing. The large 3.2" 1,229k-dot
LCD monitor allows live view monitoring and image review and the optical
pentaprism viewfinder incorporates an OLED information display and
provides 100% field coverage. The EXPEED 3 image processor also provides
a wealth of speed throughout the camera system and enables a
full-resolution continuous shooting rate of 6fps, a 1.3x DX crop
continuous shooting rate of 7fps and an expandable maximum sensitivity
to ISO 25600. The new Spot White Balance features permits selective
control over custom white balance settings and built-in HDR
automatically composites bracketed frames to produce a single image with
an extended dynamic range. The D7100 is compatible with the WU-1a
Wireless Mobile Adapter to enable wireless connectivity and the ability
to instantly transfer imagery to iOS and Android mobile devices. Housing
all of the imaging technology is a redesigned body that features
magnesium alloy top and rear covers for increased durability and
moisture- and weather-resistance. The D7100 is available as a body only
or in a kit with the AF-S DX NIKKOR 18-105mm f/3.5-5l.6G ED VR lens.

So.... Is THIS the long-awaited "D300 Replacement"? Or just one more shred of
evidence that Nikon now equates serious photography with full-frame and that a
true D300 replacement is a pipe dream? (As a Canonian, I of course ask this
question only to stir the pot and keep it boiling evenly.) ;^)

BTW, I don't think I'd be happy with the kit lens, if the best it can do at
105mm is f/51.6.

it depends on the subject. take a photo where there's very little
detail, such as a solid colour wall, and there won't be any aliasing.
take a photo of something with a lot of detail and there will be.

In theory, yes, but you /did/ see the post from someone who had taken
several thousand photos on a filter-free D800, and only seen aliasing in
a couple of them? With "consumer" rather than "quality professional"
lenses the visibility of such errors is much less likely (as lower
lenses have lower MTF at the higher spatial frequencies).

I didn't see that post. But even if the moire is not visible in every
shot, it should be clear that errors are present in a large number of
images, even if they are not visible (fake detail etc.).
On the other hand, with 24MP on a APS-C sensor the lens alone will
probably cut off a lot of beyond Nyquist detail.

That is quite true. It may not be obvious noise, but it
is "clutter" that reduces the true resolving power of
the process. When someone says they didn't see any
aliasing in thousands of images the obvious conclusion
is that they wouldn't know what it looks like if it bit
them.

Only on the worst of lenses. It won't be until the
equivalent of a full frame sensor that is greater than
175-200 MP comes along that the sensors will out resolve
typical lenses. A 24MP APS-C sensor isn't even close.

it depends on the subject. take a photo where there's very little
detail, such as a solid colour wall, and there won't be any aliasing.

And your experience using one is?
Or is your comment made based on a survey.

One of my friends, a fashion photographer, uses his D800E. His results
are fantastic. A well respected fine art photographer also uses one, and
she is quite happy with the results. The main reason I did not get one,
is that I didn't nbeed that feature for the type of shooting I do.
